Functionalism is an early school of thought in psychology that:

emphasizes the importance of the mind's functions and how it helps individuals adapt to their environment. This theory argues that mental processes and behaviors serve a purpose in helping individuals survive and thrive in their surroundings. Functionalism focuses on how mental processes and behaviors help individuals achieve their goals and navigate their environment, rather than just focusing on the structure of the mind. It also emphasizes the importance of studying the purpose and function of mental processes in understanding human behavior.
